Summaries for PRKAR1B Gene

Entrez Gene Summary for PRKAR1B Gene

  • The protein encoded by this gene is a regulatory subunit of cyclic AMP-dependent protein kinase A (PKA), which is involved in the signaling pathway of the second messenger cAMP. Two regulatory and two catalytic subunits form the PKA holoenzyme, disbands after cAMP binding. The holoenzyme is involved in many cellular events, including ion transport, metabolism, and transcription. Several transcript variants encoding the same protein have been found for this gene.

GeneCards Summary for PRKAR1B Gene

PRKAR1B (Protein Kinase CAMP-Dependent Type I Regulatory Subunit Beta) is a Protein Coding gene. Diseases associated with PRKAR1B include Prkar1b-Related Neurodegenerative Dementia With Intermediate Filaments and Carney Complex Variant. Among its related pathways are Regulation of CFTR activity (norm and CF) and DAG and IP3 signaling. GO annotations related to this gene include cAMP binding and cAMP-dependent protein kinase regulator activity. An important paralog of this gene is PRKAR1A.

UniProtKB/Swiss-Prot for PRKAR1B Gene

  • Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells.

Tocris Summary for PRKAR1B Gene

  • Protein kinase A (PKA, aka cAMP-dependent protein kinase) is involved in the regulation of lipid and glucose metabolism and is a component of the signal transduction mechanism of certain GPCRs. PKA is composed of two regulatory subunits and two catalytic subunits.
